The WhisperKOOL Platinum Split 4000 is a ductless split wine cellar cooling system designed to provide reliable cooling performance while maintaining a quiet, discreet presence inside the wine cellar.
The evaporator mounts inside the wine cellar, while the remote condenser can be positioned up to 100 feet away, providing greater flexibility when planning the location of the cooling equipment. This configuration helps preserve valuable wall space and allows the system to be adapted to a variety of residential and commercial wine cellar installations.
The Platinum Split 4000 is available with your choice of a 110V ΩMEGA H.E. Condenser or 220V Advanced H.E. Condenser, allowing you to select the configuration that best fits your electrical service and installation requirements.
The 110V ΩMEGA H.E. Condenser provides a flexible electrical configuration for installations where 110V power is preferred or required. It offers high-efficiency cooling and flexible installation options when paired with the appropriate accessories.
The 220V Advanced H.E. Condenser is designed for high-efficiency performance, ultra-quiet operation, simplified installation, and reliable operation across a wide range of ambient conditions, including extreme climates from -20°F to 120°F.
Professional HVAC-R installation is required. Failure to have the system installed by a qualified HVAC-R technician will void the warranty.
24V Thermostat Option: The optional 24V Thermostat Conversion Kit changes the standard control configuration. The standard WhisperKOOL KDT control and liquid-temperature-measuring bottle probe are not included with this option. A compatible 24V thermostat must be supplied by the customer. WhisperKOOL does not provide technical support for third-party smart thermostats.

The line set is not included with the Platinum Split 4000 system. Line-set requirements and other installation materials should be determined by the qualified HVAC-R professional based on the specific installation.
The Platinum Split 4000 has a theoretical cooling capacity of 3,650–4,315 BTU/h. Actual cooling requirements can vary depending on the specific design, construction, and environmental conditions of the wine cellar.
Factors such as glass, stone, concrete, insulation, ambient temperature, cellar location, lighting, and other heat-producing elements can increase the cooling load beyond the theoretical calculation.
We recommend selecting a cooling system with sufficient capacity to compensate for these variables. An undersized unit may run excessively, may not be able to maintain the desired cellar temperature, and can contribute to premature system failure.
For the most accurate system selection, a wine cellar heat-load calculation should be performed before ordering.
If you are unsure which system is appropriate for your wine cellar, contact Wine Appreciation before ordering.
Choosing between the 110V ΩMEGA H.E. and 220V Advanced H.E. condenser depends on the available electrical service, condenser location, installation environment, and project requirements.
The Platinum Split 4000 provides installation flexibility with the evaporator mounted inside the wine cellar and the remote condenser positioned up to 100 feet away.
If you're working on a new wine cellar or replacing an existing cooling system, contact Wine Appreciation before ordering. We can help determine which WhisperKOOL configuration is appropriate for your project.
